“It’s rare to find this many unexploded munitions at once,” said Maedomari.
“Because unexploded munitions from the Second World War are scattered across Okinawa, construction workers always use metal detectors before starting to dig the ground,” he said.
Unexploded munitions are periodically found across Japan, even in highly developed Tokyo.
Okinawa was the bloodiest battle of the Pacific war, with US forces unleashing an 83-day air and amphibious assault dubbed by locals the “Typhoon of Steel”. Some 190,000 Japanese died, half of them Okinawan civilians.
